15 - destroying a non-default loop would stop the global waitpid
16 watcher (Denis Bilenko).
17 - queueing pending watchers of higher priority from a watcher now invokes
18 them in a timely fashion (reported by Denis Bilenko).
19 - add throw() to all libev functions that cannot throw exceptions, for
20 further code size decrease when compiling for C++.
21 - add throw () to callbacks that must not throw exceptions (allocator,
22 syserr, loop acquire/release, periodic reschedule cbs).
23 - fix event_base_loop return code, add event_get_callback, event_base_new,
24 event_base_get_method calls to improve libevent 1.x emulation and add
25 some libevent 2.x functionality (based on a patch by Jeff Davey).
26 - add more memory fences to fix a bug reported by Jeff Davey. Better
27 be overfenced than underprotected.
28 - ev_run now returns a boolean status (true meaning watchers are
29 still active).
30 - ev_once: undef EV_ERROR in ev_kqueue.c, to avoid clashing with
31 libev's EV_ERROR (reported by 191919).
32 - (ecb) add memory fence support for xlC (Darin McBride).
33 - (ecb) add memory fence support for gcc-mips (Anton Kirilov).
34 - (ecb) add memory fence support for gcc-alpha (Christian Weisgerber).
35 - work around some kernels losing file descriptors by leaking
36 the kqueue descriptor in the child.
37 - include sys/syscall.h instead of plain syscall.h.
38 - check for io watcher loops in ev_verify, check for the most
39 common reported usage bug in ev_io_start.
40 - chose socket vs. WSASocket at compiletime using EV_USE_WSASOCKET.
41 - always use WSASend/WSARecv directly on windows, hoping that this
42 works in all cases (unlike read/write/send/recv...).
43 - try to detect signals around a fork faster (test program by
44 Denis Bilenko).
45 - work around recent glibc versions that leak memory in realloc.
46 - rename ev::embed::set to ev::embed::set_embed to avoid clashing
47 the watcher base set (loop) method.
48 - rewrite the async/signal pipe logic to always keep a valid fd, which
49 simplifies (and hopefuly correctifies :) the race checking
50 on fork, at the cost of one extra fd.

53 - INCOMPATIBLE CHANGE: ev_timer_again now clears the pending status, as
54 was documented already, but not implemented in the repeating case.
55 - new compiletime symbols: EV_NO_SMP and EV_NO_THREADS.

73 - fix #3 "be smart about timeouts" to not "deadlock" when
74 timeout == now, also improve the section overall.
75 - avoid "AVOIDING FINISHING BEFORE RETURNING" idiom.
76 - support new EV_API_STATIC mode to make all libev symbols
77 static.
78 - supply default CFLAGS of -g -O3 with gcc when original CFLAGS
79 were empty.
